5404501966 crosvm fix stale balloon stats
Stale balloon stats results can be returned from a stats request for the
following reasons:
* The initial stats buffer from the guest is posted to the
  balloon_host_tube without a request.
* Balloon stats requests can fail because the balloon device isn't
  completely set up yet; writing a stats request to the tube without
  reading the response.
* Balloon stats requests can time out, returning an error. When the
  balloon stats are eventually computed, they will be queued to the tube
  without a read to consume them.

Possibly other reasons too.

This CL fixes this by adding an id to the balloon stats request. The id
is then returned with the computed stats. When consuming stats results
from the balloon_host_tube, we check that the ID is the one we expect,
if not, we keep reading from the tube until we do.

8bf5dcade3 virtio: video: Add support for prepending SPS/PPS to IDR frames.
This CL adds support for the VIRTIO_VIDEO_CONTROL_PREPEND_SPSPPS_TO_IDR
control to the virtio encoder. When this control is enabled SPS and PPS
NAL units are prepended to IDR frames, to improve the resilience of
encoded video streams.

Note: Currently the libvda backend always prepends SPS and PPS NAL
units to IDR frames. This behavior can not be disabled, so when
querying this control it will always be reported as enabled. Trying to
set the control to disabled will result in an error.

When VIRTIO_GPU_BLOB_FLAG_CREATE_GUEST_HANDLE is not set, the check

GpuCommand::ResourceAttachBacking.

When VIRTIO_GPU_BLOB_FLAG_CREATE_GUEST_HANDLE is set, the check may not
be correct because upstream kernel made the limit configurable recently

  https://patchwork.freedesktop.org/patch/438905/

It should be better to just remove the check and let the kernel does the
validation.

This allows all other platforms to build without depending on
`third_party/adhd/cras/client/libcras`, which is a prerequisite for
externalizing crosvm.

An empty libcras_stub crate is provided to keep cargo happy in external
builds.

To build with cargo against libcras, the setup_cros_cargo.sh script

06d7c9edb9 virtio: video: Recreate encoder on framerate changes.
CL crrev.com/c/3005194 introduced changes to the encoder to allow
dynamic framerate changes even when there are already resources queued
in the input or output queue. As a side effect the encoder is only
recreated if any parameters besides the framerate change.

Unfortunately the above checks assumes that changing the framerate will
never influence any of the other parameters, which isn't always
correct. The requested H.264 level is adjusted to conform to the
minimum requirements for the selected bitrate and framerate. We can't
dynamically adjust the H.264 level during encoding, but as long as we
don't have any resources queued yet we can recreate the encoder to make
sure the H.264 level is properly adjusted if required.

da4e8a9fcd arch: move resume_notify_devices out of Bus
The devices to be notified on resume are unrelated to the functionality
of Bus, which is looking up devices in an address space. Additionally,
each Bus instance had its own list of devices to notify, although in
practice, only the one in the I/O bus was used.

Move the resume_notify_devices list into RunnableLinuxVm instead.

71435c1aea devices: virtio: iommu: implement VIRTIO_IOMMU_F_INPUT_RANGE feature
In VT-d, the IOMMU hardware can translate guest physical address that
is no more than MGAW (Maximum Guest Address Width) which is reported
from the VT-d Capability register.

We pass this information to the guest IOMMU front driver so that it
can allocate appropriate IOVA.

VT-d indicates that "implementations must support MGAW at least equal
to the physical addressability (host address width) of the platform".
Thus we take the Physical Address Bits that is reported by
CPUID.80000008H as the minimum MGAW.

775aa4f594 virtio: gpu: add support for non-blocking fence synchronization
A completed fence callback is set in Rutabaga. When the callback
is executed, the descriptor associated with the fence is immediately
marked as used and the control queue is signalled.

As of now, the callback is still called in the main worker thread
when poll_fence() is executed, but once we enable the async callback
feature in virglrenderer, the callback might be called from another
thread. This is the reason everything is protected with mutexes.

The completed_fences hash map keeps track of the latest completed
fence for each context to avoid any race condition.

f95a1df7d2 virtqueue: Add missing fences
These values are either written by the device and read by the guest or
vice versa.  Either way, since these could happen simultaneously on
separate cores we need fences to prevent the CPU from re-ordering loads
and stores.

"get" methods use acquire-load semantics while "set" methods use
release-store semantics.  This also matches what we were already doing
for "get_avail_index" and "set_used_index".

With this it should be possible to re-enable the check for
VIRTIO_AVAIL_F_NO_INTERRUPT but we'll do that in a separate change since
we need these changes no matter what.

563008fc99 virtio: video: Support dynamic framerate changes in encoder.
Currently changing the framerate during video encoding will always fail
once resources are queued on the input or output queue. This CL makes
adaptations to the crosvm encoder to fix dynamic framerate changes.

To support dynamic parameter changes the crosvm encoder will now
properly check whether values actually changed, and only report an
error if we're trying to change static parameters during encoding (such
as the output format). As a side effect this greatly reduces the amount
of times the Chrome encoder is recreated; parameters are configured
one-by-one through virtio and each parameter change requires us to
initialize an encoder, as we only know the coded size after the
initialized encoder calls the RequireBitstreamBuffers() callback.
